IPC: H04B10/524
Filed: 1998-07-09
Abstract: PROBLEM TO BE SOLVED: To transmit a signal whose transmission rate is as high as more than 40 Gbit/s over an ultra-long distance of 6000 km or over. SOLUTION: An optical transmitter 10 outputs a signal light with an optical pulse width of 8 ps consisting of optical soliton with a transmission rate of 40 Gbit/s to an optical transmission line 12 where many transmission optical fibers 14 are connected in series respectively through optical amplifiers and dispersion compensation fibers 18 are inserted at a proper interval. The dispersion compensation fiber 18 is an element that reduces accumulated wavelength dispersion by the transmission optical fibers 14 to almost nullify it. The signal light sent through the optical transmission line 12 is given to a optical receiver 20 where the signal is reception-processed. The wavelength dispersion of the transmission optical fiber 14 causes a wavelength dispersion of 0.23 ps/nm/km or over at a signal wavelength of 1552.8 nm.  The dispersion compensation by the dispersion compensation fiber 18 is 10 ps/nm-40 ps/nm.

Title: Method for hot edging of metal slab
Inventor: HIROSE MINORU
IPC: B21B37/00
Filed: 1987-08-05
Abstract: PURPOSE:To improve the yield and shape quality of products by performing rolling by reducing a rolling speed within a range where a rolling time of a min. number of reversible rolling passes and increasing edging amounts at a metal slab end. CONSTITUTION:Hot reversible rolling of a metal slab 1 is performed by installing a horizontal rolling mill H having horizontal rolls 3 between vertical mills V1, V2 having vertical rolls 2, 4, respectively. In that case, a rotating speed of the rolls 2, 4 of the mills V1, V2 is reduced to perform edging. Thus, a slab width regulated by a max. rolling load is widened because rolling loads are reduced, so that the number of passes is reduced and a crop loss at a slab end is reduced without sacrifice of a rolling time and a recession amount at the slab central part is reduced. Therefore, the yield and shape quality of products are improved.

Abstract: PURPOSE:To reduce driving horsepower of a compressor by driving the com-pressor at the maximum capacity for a specified time when the engine brake is applied from a state where engine speed is above an idling up stopping engine speed at the time that an air conditioner is used. CONSTITUTION:At the time that an air conditioner is used while the vehicle being in operation, when as engine speed signal from an engine speed detect-ing means 1 is above a first set engine speed, for example, 2700rpm, a control unit 6 outputs an idling up stopping signal for the air conditioner to an idling engine speed adjusting means 3, and when the engine speed sig-nal is below a second set engine speed, for example, 2200rpm, the control unit outputs an idling up starting signal to the idling engine speed adjust-ing means. In this case, when the engine speed signal is above the first set engine speed, and the engine brak is judged to be applied from output of an throttle opening detecting sensor 9 or an idling opening, the control unit 6 controls the compressor 5 for the air conditioner 4 to be driven at the maximum capacity for a specified time, and thereby the driving horse-power of the compressor 5 can be reduced.
